A file is an organized collection of data that’s stored in a single item. The data can be text, video clip or program. Each file has a name that identifies it. Files names are generally followed by the period of three letters called an Extension. In most cases, the program that you are using will automatically add the extension. You may or may not see the extensions depending on how your computer is set up. Example of file extensions or file types used in Windows and DOS are shown in the table below:
